In the Diploma thesis called "Research of seasonality in the animal dental cement and the use of this method in archaeology", I devote myself to one of the most reliable methods for determining the age cementochronology, or the analysis of increments of the dental cement. By using the method, it is possible to relatively accurately evaluate the age of an individual and to determine the death season, and thus we penetrate deeper not only to problems of palaeoecological conditions of archaeological situations, but also to economical-social relationships of then populations. Cementochronology also allows trace hunting and settlement strategies, i. e. when and for a what purpose the specific site was settled. The Diploma thesis summerizes previous knowledge about the method and compares it with the results obtained by the analysis of increments of the dental cement, which was applied on referential zoological and archaeozoological material.
